How to calculate plastic, elastic section modulus and Shape Factor of a cross-section?

[@JitendraSingh-o6h1v]

sir, plastic modulous part is not clear. since when i do using formula
(A/2)(y1+y2 ), the answer is different

[@akagantaemmanuel3372]

please can this same approach be applied to a general sectiion

[@eeshansharma2926]

Yes sure

[@karenmaepanaguiton2499]

Is the location of plastic neutral axis and elastic neutral axis the same?

[@SKIZZ8506]

Not always

[@sathiyanarayananp7822]

Nice explanation

[@skkjgff6130]

Thank you sir 👍👍👍👌

[@dusialex]

question ,for calculating the elastic section modulus why do not use y bottom as you have calculated?

[@anjuanju5556]

Y maximum is required. Y top is greater than y bottom

Thank you Sir

Can a steel section in compression reach yield point

[@amanthakur2040]

no bro

[@dtej1193]

Sir thank you so much for the video I have 1 doubt is plastic neutral axis same as equal area axis

[@MohammedFasilM]

👍🏻

[@peternungari487]

I have doubt in your calculations.. some of your points are not clear at all

Please tag the time and we can discuss

[@elvismasinde4321]

@@BoldLearning The calculation for y-bottom has an error the answer is 259.65mm

[@zyeaser]

@@elvismasinde4321 The calculation is correct. The width of the bottom flange is 150 (not 50).

Your explanation is not clear sir sorry. There is so many unobvious part. You just wrote and skip and skip and skip fastly. May you explain please ?

[@nom6758]

Why didnt you calculate Syy?

[@sonehaantoniop8371]

because the i- section is symetrical about y-y axis
